I was visiting California for my little sister's graduation. My family and I went to Disneyland after her graduation. The UFO was seen in the evening at Sleeping Beauty's Castle during the end of the night fireworks show. During the middle of the fireworks show, my family and I, along with the hundreds of people at Disney, noticed a shape approaching the castle coming from the West. The shape became evident that it was in the shape of a saucer as it flew closer to the castle. Hundreds of eye witnesses and myself became very quiet as it flew over us. My best guess is it was maybe 500 ft above us as we could all see it was silver, metallic and it had a series of lights on the underside of the craft that spiraled in a counter-clockwise direction. The craft never made a sound as it flew over us. The flight pattern was smooth and linear. The craft never stopped. It continued to fly through the fireworks, over the castle and onto the horizon. I tried to video tape! it with my little digital camera; however, all you could see was the lights swirling in the counter-clockwise direction and could not quite make out the shape of the craft because it was too dark. I remember listening to a bunch of the surrounding people whispering and asking if that was a UFO as it approached the castle. There is no doubt in my mind that what we saw was not an airplane, helicopter or any other flying craft we typically see in the sky.
